caudatum. What I have seen as No. 180, is decidedly not S. Caffrorum, and it 
is very likely that the Eritrea and Urundi specimens are also distinct and rather 
belong to the caudatum group. Schweinfurth (PI. qused. Nilot. 44) enumerates 
S. Usorum as cultivated at Khartum and sold under the name “ es-ahmar ” and 
in a glabrescent form as “ khimegi .”

32. A. S ., var. yemensis, Koern. in Baumann, Massailand, 295 
(name) ; in Bull. Herb. Boiss. ii. App. ii. 11. Panicle erect, con- 
tracted, oblong, about 10 in. by 2 in. ; branches slender, flexuous, 
but erect. Glumes pale yellowish. Grain white.

According to Koernicke also in Yemen, where it is grown as fodder for cattle. 
33. A. S ., var. Ziegleri, Busse & Pilger in Engl. Jahrb. xxxii. 186. 
Panicle contracted, 6-9 in. long ; rhachis not exceeding the middle 
of the panicle ; branches compact, erect, the lower short, the upper 
umbellately arranged, 2-3 in. long. Glumes rotundate, straw- 
colour, then brown, shining, strigillose at the base and sides. Grain 
exceeding the glumes, subglobose, 2 lin. by 1J lin., whitish.

Evidently closely allied to var. Schumannii and like it a member of the 
caudatum group. 
Several Sorghums cultivated on the middle Niger are described 
by Dumas (in Agric. Prat. Pays Chauds, v. i. 459-161) under their 
vernacular names. They are, apart from those mentioned already : — 
Bemberi. Panicles very long. Glumes pointed, black. Grain 
equalling the glumes, quite free from them, pointed at both ends, 
brilliant white. Dumas places it next to “ keniki ” (see below) and 
it is no doubt one of the guineense or margaritiferum group. 
Hiassa-Kala. Panicle lax, flexible, with long drooping branches. 
Glumes white, slightly tinged with red, tightly enclosing and equal- 
ling the grain. Grain dark red, flat on one side, gibbous on the other. 
This is cultivated for its sweet stems, particularly in the Macina and 
Malinke country. The juice of the stem contains up to 12 per cent, 
of cane sugar. Dumas refers it to “ Sorghum saccharatum .” 
Keniki. Culms slender, 12 to 15 ft. high. Panicle up to 2 ft. long, 
with drooping branches when mature ; branches up to 8 in. long. 
Grain white, slightly spotted with red or black, oval, flattened, free 
between the spreading glumes and slightly exceeding them. The 
most common Sorghum grain in the markets of Bambara and
